A method has been developed for making americium- beryllium neutron sources by the reduction of americium oxide with beryllium. This method has a certain number of advantages over those using a target-emitter mixture without formation of the definite compound AmBe{sub 13}. An emission of 3. 75 x 10{sup 6} n/sec. is obtained with 1 gram of alloy having a volume of about 0.3 cm{sup 3}. The yield of such a source is 2 x 10{sup 6} n/sec/Ci of emitter.

Cette methode offre un certain nombre d'avantages par rapport a celles qui utilisent le melange cible-emetteur sans formation du compose defini AmBe{sub 13}. Une emission de 3.75 x 10{sup 6} n/s est realisee avec 1 gramme d'alliage occupant un volume d'environ 0,3 cm{sup 3}. Le rendement de telles sources est 2 x 10{sup 6} n/s/Ci d'emetteur. (auteurs)
